extending from side to side, rigidly secured to the car frame and toeach other which will be of light weight material and will a' fford amaximum head room or clearance on the inside of the car.

One particular advantage of this construction is that while thecarlines, roof sheets and seam caps are secured together by rivets,should the rivets become loose or the heads sheared in service, waterwill not readily drain into the car as all of the rivet holes over thecar body are in a horizontal plane.

While the preferred form of this invention is illlustrated upon theaccompanying sheets of drawings yet minor detail changes may be madewithout departing from the scope thereof.

In the drawings:

Figure 1 is a top Ian view of a portion of a car roof embodying thisinvention, with parts broken away.

Figure 2 is a view in vertical section, taken on the line 2-2 of Figure1, looking in the direction of the arrows.

Figure 3 is a view in side elevation of Figure 1 with parts broken away.

Figure 4 is a view in section taken on the line 4-4 of Figure 2.

Figure 5 is a view in section taken on the line 5-5 of Figure 2.

Figures 6 and 7 are views similar to Figures 4 and 5, of a modified formof construction. a

Figure 8 is a view in side elevation of the running board saddle shownin Figure 6.

The embodiment of this invention as illustrated comprises a plurality ofroof sheets by rivets as shown. The adjacent edges of their ends restingupon the upper surface of. es

the side platesextending therebeyond and bent downward, as shown. Thebodies and the adjacent edges of roof sheetsare supported upon theflanges 5 of the carlines with the flanges 3 of the roof sheets engagingthe parallel sides of the carlines for preferably about half the heightof the carline. To provide a water-tight closure and give additionalrigidity to the seams, seam caps 6 of inverted U-shape are a plied overthe carlines having out turned anges 7 at the bottom of the sides, whichrest 11 on the body of the roof sheets and hold t e roof sheet flangesin engagement with the side walls of the carlines. These seam caps arepreferably pressed from a rectangular sheet of nietal and extend fromside to side resting at their eaves ends upon the roof sheets over theside plates and extending therebeyond and bent down over the tops of thecarlines and terminated therewith, as shown. The seam caps are of reaterheight than the carline at the ridge an are gradually reduced in heightas they approach the eaves, until the t'ops of the caps en age the topsof the carlines over the side p ates, the flanges froih the side wallsof the caps increase in width in proportion to the decrease in height ofthe caps, thereby not only utilizing the surplus metal formed indecreasing the height but also adding additional strength to the cap.The caps are preferably secured to the carlines and thereby securing theroof sheets by a plurality of rivets 8 between the ridge and eaves whichpasses in a horizontal direction through the carline and cap above theroof sheet flange and at the eaves by rivets 9 passing through the sidelate, roof sheets and out turned flanges of t e caps.

Figures 5 and 6 illustrate a modification in which the out turnedflanges 5 of the carlines are provided with a continuous crimp orcorrugation 10, the body of the roof sheets havin a similar corrugationor crimp 11 to rest t ereon and the out turned flanges 7 of the caps areprovided with a like corrugation or crimp 12, to provide a more perfectjoint between the three parts and prevent the edges of the roof sheetsfrom pulling out between the carlines and caps. If desired the cap sidewalls may have an oflset 13, to accommodate the roof sheet flanges andallow the side walls to snugly fit the side walls of the carlines.

In this type of roof it is preferable to support the running boards 14by saddles in the form of plates 15 having a portion riveted to the topof the seam cap with a portion 16 extending down over the side of thecap and secured thereto by the rivets securing the cap to the carlineand a portion 17 on the other side stuck up and extending beyond the capto support the underside of the running board above the rivets on thetop of the cap and to which, portion the running boards may bebolted asshown in Figures 1, 2 and 4.

Another form of running board saddle is illustrated in Figures 6 and 8which comprises a late 18 of inverted U-shape, whose side wal s areshouldered to rest upon the topof the seam cap and are secured to theside walls of the caps by horizontal rivets above the top of thecarline. The running boards rest upon the top of the saddles and arepreferably bolted thereto as shown in Figure 6. The side walls of thesaddle being cut away, as at 19, on each side for the, application of awrench for operating the,

nut on the bolt as shown in Figure 8.

Another advantage of this construction is that the caps are not requiredto be riveted throughout their entire length to the carline to form arigid structure. The caps and roof sheets are riveted to the sideplates, with the caps in contact with the carlines and closely holdingthe said flanges between them, and it is only necessary to rivet thecaps and carlines for about onehalf the distance from the ridge to theeaves. The rivet holes over the body of the car are in a horizontalplane and therefore do not afl'ord a ready access for water draininginto the interior of the car.

The form of carlines extending over the side plates provides a means forventilation and the down turned ends act as bafies to the entrance ofrain or water. As all metal roofs will sweat when there is a difierencein temperature between the interior and exterior of the car this form ofventilation tends to maintain an equal temperature on both sides of theroof sheets.
